CAR-REPLACER.

Specification of Letters Patent.

Patented July 20, 1920.

Application filed October 7, 1919. Serial No. 329,035.

To all whom it may concern H Be it known that 1, JOHN JACOBSON, a citizen of the United States, residing at Rockford, in the county of Vinnebago and State of Illinois, have invented certain new and useful Improvementsin Car-'Replacers, of which the following is a specification.

This invention pertains in general to railways, and has more particular reference to car replacers of the rigid block type.

The primary object of the present invention is to provide a car replacer of generally improved construction, including two block elements, one adapted only for use outside of the rails and the other inside thereof. My invention contemplates the building of these blocks in such novel manner that they will serve positively and eflectually to guide a derailed truck into the proper position on the rails.

Another object of my invention is to provide replacer blocks adapted to be associated with the rails in a novel manner and including side flanges which constitute guides cooperating with shiftable guide bars on the blocks for guiding the wheels into position above the rails.

Still another object resides in the provision of a replacer block having a detachable rail clamp or flange which may be easily replaced by a new one in the event that it is broken under the severe side thrust often imposed while replacing a car.

My invention further contemplates the provision of novel means for supporting the blocks at different elevations in accordance with variations in the height of rails.

Other objects and attendant advantages will be appreciated as the invention becomes better understood by reference to the following description when considered in connection with the accompanying drawing, in which Figure 1 is a plan view illustrating diagrammatically an arrangement of my improved car replacer blocks in working position;

Figs. 2 and 3, plan views of the outside and inside blocks, respectively, with the rail clamps detached;

Figs. 4 and 5, side views shown in Figs. 2 and 3;

Figs. 6 and 7, Vertical longitudinal sectional views through the parts shown in Figs. 2 and 3 respectively;

Figs. 8 and 9, front views of the outside and inside replacer blocks respectively; and

of the p arts Figs. 10 and 11, cross-sectional views taken on the lines 1010 and ll1l of Figs. 4 and 5, respectively.

As mentioned above, my invention contemplates the provision of a pair of car replacer blocks, one adapted only for use at the outside of the rails and the other inside thereof. This is for the purpose of constructing each block to suit the peculiar conditions and requirements incidental to replacing or rerailing a car or locomotive truck, as will be presently seen. Referring to the drawing, it will be observed that the outside replacer block is designated generally by the character 14 and inside block by 15. Each block is cast integral to the requisite shape except for the rail clamping or bracing means, which I prefer to make as a separate detachable element. Considering first the construction of the outside block, it will be observed viewing Fig. 6, that this block is shaped to provide an inclined top surface 16, the high end of which is supported at the proper elevation by means of a detachable shim 17. The outer vertical sides 18 of this block are substantially straight longitudinally there of and converge toward the high end. Above each side 18 the body of the block is extended outwardly providing a ledge 19 adapted to overlie and rest .upon the top of a rail. The side edges of this block are further shaped to provide upstanding flanges 21 extending substantially coextensive with the length of the block, the high end of each flange extending over and beyond the inner side of the rail with which the respective flange cooperates as shown in Fig. 1. The block is held in cooperative relation with the rail by means of a railengaging flange or element designated by character 22. This element 22, detachably secured to the block 16 by suitable means such as a bolt 23, is shaped to provide at each side of said block and in longitudinal alinement with the sides 18 and ledges 19, a rail-engaging flange 24 adapted to fit over the head of a rail and hold the block in juxtaposition thereto. In this instance, the supporting shim 17 rests on the base of the rail and supports the block medially at its high end. A shiftable guide bar 25 pivotally mounted intermediate its ends at 26 on top of the block and shaped to conform to the inclined surface thereof is adapted to be secured in any of a plurality of positions in which its forward end 27 is be easily replaced by a new one.

tively roll onto the rail with the wheelfiange inside thereof. It is preferred that the rail-engaging element 22 shall be of cast steel, while the block 14 will be cast of iron. Inthe event that the element 22 is broken from excessive strain, this part may Supporting shims 17 of diflerent height are supplied so that the replacer block may be supported at the proper height regardless of variations in rail sizes.

The inside replacer block is very similar in construction to the outside block except that each upstanding flange 31 is of greater width than the corresponding flange 21 of the outside block and is shaped to provide a flat upper surface upon which the tread of the car wheel is adapted to roll. Each flange 31 is shaped to extend entirely over the respective rail with which it is associated, as shown plainly in Fig. 1, so that such flange serves not only as an outer guide for the car wheel, but also as the supporting surface upon which the tread of the wheel rolls while being returned to the proper position over the car rail. The inner block is equipped with a removable rail-attaching element 32 similar in construction to the element 22 above described. As shown plainly in Fig. 9, the part 32 conforms on its upper surface to the shape of the. ledges 31 and is equipped with depending rail-engaging flanges 83. A shiftable guide bar. 34 similar to the bar 25 mentioned above, is adapted to be locked with its upper or forward end in operative relation with either flange 31, by means of a pin or bolt 35. noted that the upper or forward end of the 'bar 34l, together with the adjacent flange 31,

form converging guides which will lead the flange of the wheel 36 into proper position at the inner side of the rail. By constructing the blocks in the manner described they may be quickly attached. to the rails and firmly held in operative relation thereto. It'will be further noted that the upstanding guides at the side of each block andthe shiftable guide bars form converging guides which positively lead the flanges of both car wheels to the inside of the rails so that the wheels will drop into proper position. thereon. It is preferred that the blocks each be cast to the desired shape and reinforced by suitable longitudinally extend It will be ing ribs as indicated in cross section in Figs. 10 and 11. j

It is believed that the foregoing conveys a clear understanding of the principles and objects of my invention, and while I have illustrated and described but a single working embodiment thereof it should be undersize to properly accommodate theinclined block to the size and shape of the rail.

2. A car replacer adapted for use only at the outside of either rail, comprising a base having an inclined top wider at its low end than at its high end and having an upstanding flange at each side extending substantially co-extensive of the length of the block, the block so shaped that its inclined surface extends over and to the inner side of each rail when in operative relation thereto, and each flange extending over and beyond the inner side of each rail when associated therewith.

3. A carreplacer comprising a block having an inclined top, means at each side of the block for holding it in juxtaposition to a rail, an upstanding flange at each side of the block for guiding a wheel longitudinally thereof into cooperative relation with the rail, and a guide bar pivoted intermediate its ends on top of the block and adjustable about its pivot to position its forward end in end, an upstanding guiding flange along each side of each block, the'latter flanges of both blocks terminating at their high ends substantially in alinement with the inner edges of the respective rail head with which each block is associated, and a shiftable' guide bar on each bloclradapted to define with either guiding flange thereof a converging guideway for guiding the flange of the car wheel into proper position over the rail V'JOHN JAOOBSON, 7
